Which components of the force create Rotational motion?

AI Thread Summary
Rotational motion is influenced by specific components of force, but understanding it requires active engagement with the problem. Forum participants emphasize the importance of showing prior attempts at solving the question to facilitate effective assistance. Patience is advised, as replies may take time, and providing detailed context can lead to quicker, more useful responses. Engaging with the problem independently enhances learning in physics. Overall, collaborative problem-solving is encouraged for better understanding of rotational dynamics.

Welcome to PF;
How have you attempted to answer the question yourself?
 
Yes but.. I don't know the answer can you tell me if you know ?

Pls answer
 
Please show me what you tried.
If you don't provide the information requested I cannot help you.

The way to get the most out of this forum is to, first, show us your working as best as you can manage. Then we can help you over the stuck part. The idea is that you will learn physics best by doing the problem yourself.

Also try to be patient when waiting for replies - in general we will not be waiting by the computer for you to get back and answer questions. It is likely that you will not get a reply for 10-20 hours. Thus, the more you can tell us about your problem, at the start, and how you have been thinking about it the sooner you can get a useful reply. (You should factor this into your thinking when you post a question too.)

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
